(low to midpolarity phase, Crossbond® cyanopropylphenyl dimethyl polysiloxane)
Similar Phase(s): DB-1301, DB-624, VF-1301ms, VF-624ms, CP-1301, ZB-624
The unique polarity of the Rtx®-624 column makes it ideal for analyzing volatile organic pollutants. Although the Rtx®-502.2 column is recommended in many methods, the Rtx®-624 column offers better resolution of early eluting compounds. The Rtx®-624 phase produces greater than 90%, resolution of the first six gases in EPA Methods 8260 and 524.2. This stationary phase is especially well-suited for EPA Method 524.2 since it resolves 2-nitropropane from 1,1-dichloropropanone, which share quantification ion m/z 43 and must be separated chromatographically.
